Did you know that different types of lasers have different pulse pedestals in terms of pulse energy? For some lasers, this pedestal can be a significant portion of the total pulse energy, as much as 40%, and as long as a few hundred picoseconds (see figure). To find out how much pedestal a laser has, you need a high-contrast autocorrelator like the pulseCheck SM Type 2. With it, you can measure pulse contrast up to seven orders of magnitude (peak to baseline) and pulse durations up to one nanosecond.
For an example of how you can control and use pulse contrast with different laser settings, we invite you to read the recent paper by Peter Kazansky (University of Southampton, UK) on ultrafast laser writing in silica glass.
